IMPROVED VMACHIN'IEI FOR 'UPSETTING- TIRES, AXLE-TRBES, 8cc.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it'fmay concern Be it known that I, ORLANDO PATEE, ofYpsilanti, in the county of Vashtenaw, and State of Michigan, haveinvented a new and improved Machine for Upsetting Tires, Axle-Trees,85e.; and I do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the accompanying drawings, making a part of thisspecification, in which- Figure l is a side elevation, the wall or frameofthe machine heilig removed in tln'ee places, and the interior parts atthose points shown in section.

Figure 2 is a plan, the floor or platform of the machine being brokenaway in several places for a similar purpose.

The object of this invention is to vconstruct a machine for the purposeof upsetting tires, 83e., which shall operate eiiectively, and withgreater convenience than any heretofore employed.

To this end the eccentrics that hold the tire are al made to be operatedby the movement of a single' venient manner.

In connection with this improved construction and arrangement of theparts referred to, a new and improved method of constructing theeccentrics is employed, whereby they are rendered much cheaper and moredurable than heretofore.

In the drawings- A represents the frame of the machine;

- B B', the clamps that hold the`tire or other article, one of themscrewing toward and -from the other, by means ofa bami-screw, I);

C C, the boxes, which cover and'protcct all but the faces of theeccentrics, each box. having a removable cover, O, held in place bybuttons c c; v

D D, the four eccentrics, which take hold of the ends of the tire, orother metallic article, and compress it longitudinally;

E, aplatform, supporting two of the eccentrics D D2, and the clamps BB', and capable of sliding longitudinally by the operation of a lever,L;

F, another platform, support-ing the other twoeccentri'cs D D3, andlikewise sliding longitudinally by the action ofthe lever I.; and

G, a shalt, covered and concealed bya box orhonsing, H, and capable ofbeing rocked by lever or levers L L Ihe function of shaft G is twofold:first, by means of an eccentric, g, to give a reciprocating motion to abar, I; and secondly, to give a similar motion to plat- -form E,throwing said platform to the left (tig. l) when the handle of lever Lis thrown to the left, by means of a shoulder, t', which strikes againstthe end of the platform, and dra-wing said platform to the right again,when said handle is thrown to the right by means of hooks h h, attachedto the platform, and ratchet-teeth a a, on the ends of the shaft,adjacent to levers L L.

It will b e here observed that the lever, as it is rocked,

4nearer to platform kE, and be fixed in that position,

while, every throw of said lever to the right, it shall move toward theright, together with the platform E. In other words, every throw of thehandle of lever L to the right, (tig. 1,) slides both platforms F andEtoward the right, while during every movement of said handle to theleft, platform F remains xed, and platform E moves to the left towardsit, thus bringing the two platforms nearer together, and upsettingthe/tire, or other article held by the clamps B B'.

I will now more particularly describe themechzm-- ism by which this iseffected.

The har I extends the whole length of the machine,.

and under the platform F, has a transverse notch or gain on its upperside, through which works a sliding wedge., fm, actuated by a weight,IV, the -wedge being held in connection with platform F, by means of aguide-groove, o, and a spur upon the under side of the platform,projecting into the groove. v

As the bar is forced toward the left, (fig. 1,) the weight draws thewedge into the slot in it, and thus fixes them' in that new positionwith relation to platform F.

Now, when the lever is thrown to the right again, it carries bar I andplatform F both to the right with it, and, as it does so, another wedge,n, actuated inthe opposite direction by a weight, W, slides into a gainin the under side of platform F, and between the shoulder of such gainand a rigid part, a', of frame A, and holds platform F in the newposition with relation to the frame In other words, the two wedges actas choclts.

When, by the left throw of the lever, platform E is moved towardplatform F, wedge m slides into the gain in bar I, and chocks the twoplatforms in that posi# tion; and when, by the right throw of the lever,platforms E and I are moved to the right, wedge n slides into` the gainon the under side of platform F, and

lof chains 7.', withdraw the wedges from the slots or E F, that when thelevers K K are" depressed to a con' siderable distance, so as towithdraw thewedges m n, ,then the action of the levers K K upon the bentpart p', will move the levers N N, and thereby draw the platform F awayfrom the platform E.

O is a link-or bent rod articulated to the sides of platform F, at f',and provided with a shoulder, o', which, when this platform is drawnaway from the other, to the proper point, falls by its own weight, andlocks over thetbeam a', so as to hold' the platform in that position,but which is itself thrown up, and unlocked by the action of a cam, i,on the bar I, at the first movement of lever L to the left, the inclinedside ofthe cam'striking under the shoulder o, raising vthe latter abovethe beam a, and libelating the platform.

d d are the vertical shafts of the four eccentrics D T, a treadlearticulated to the end of the block It,-

as shown at .t, in such a manner, thatby depressing the outer end of thetreadle, the block will `be rocked on its pivot, the springs throwndown, and the eceen trios D Dl turned on their vertical axis, and causedto grapple the tire, axle-tree, 85o., and hold it firmly during themovement of the two platforms by the `lever L, as above described.

The construction of the eccentrics DDl D2 D3 is a matterof someimportance. If made of steel, they are unnecessarily expensive, and ifmade of iron, they become pressed out of shape themselves, and have tobe often renewed. I, therefore, make the body ofthem, as shown by thelines e e, of iron. Into one side of the iron part, I insert acorrugated `steel facing, c, fixing it in place by means of 'a dovetail,fur', and, if necessary, bolts yor screws c.

The operation of the machine is simple and convenient.

As soon 4as one tire, axle-tree, or other article is upset, 'theVoperator removes his foot from treadle T, thus' releasing `theeccentrics D D' D'l D. H e then unscrews the part b, and removes thetire, shown in red lilies, fig. 2. Next, he goes round to the other endof the machine, and presses his foot on` treadle M, which removes thewedges from their gains, and at the same time draws platform F to theleft until the hook o', 'on bent bar-O, drops overthe beam a', and locksthe platform in that position. He then throws thehandle of lever L tothe right as 'far as it will go, separating the jaws D vD3 from the jawsD D2 as far as possible, after which 'he' inserts the new tire, or otherarticle to be upset, clamps it by a movement of screw b, and brings allthe eccentric gripers D DD2 D3 to bear upon it by a sngle'downwardmovement of treadle T. He is now-'ready to operate lever L, the firstmovement of which t o` the left, throws up h tr O,- and releasesplatform F, and at the same time pushes platform E to the left,`partially upsetting the tire, &c.

The return movement of the lever draws back platform E, and withitplatform- F,and wedge n slides behind the latter, preventing it fromlosing the ground thus gained.

The next `movement of lever L to the left, further advances the processof upsetting the tire, and the operation is thus continued until thetire is fully upset, or until it becomes necessary to adjust it again inthe 'eccentric-jaws'and repeat the process.

Having thus described my invention, v What I claim as new, and desire tosecure by 'Letters Patent, is-

1.l The combination of platforms E F with har I,

`wedges 'nt 11*eccentric shaft G, lever L, and hooks hh,

all constructed 'to operate substantially as and for the purpose setforth. i

2. Connecting the wedge m to the platform F by means of the slot o andthe spur of the platform projecting into it, when the parts referred toare constructed and operated as and for the purpose set forth. 3.Operating simultaneously all the eccentrics D Dl Dz D3 `ofanupsetting-machine, by means of the parts Q S It T, substantially as andfor` the purposes described.

4. The hooked link or bar O, when constructed to operate in connectionwith platform F, bar I, beam ai', and cam t', substantially as and forthe purposes described.

5. The combination of weighted treadle M, with weighted leversK K,chains la k, wedges A11i-)aand weights XV W', substantially as and forthe purposes set forth. 6. In combination with the parts M K K la k m nW W', the bent levers N N, constructed ito operate in connection withplatform F, as described.
